Zebra RFID执行doInBackground()时出错，java.lang.ClassCastException: com.zebra.rfid.RfidServiceMgr无法强制转换为b.a.b.a

Question

我正在编写一个使用RFIDAPI3Library的Flutter/Android应用程序，它大致基于SDK示例应用程序。当我在调试模式下运行它时，它可以成功运行，但是当我在发布模式下运行它时，我得到一个错误。在debug vs release中运行它会导致这样的错误，有什么不同？如有任何想法，我们将不胜感激

将这两行代码(minifyEnable、shrinkResources)添加到模块的build.gradle文件中似乎已经解决了这个问题

buildTypes {
        release {
            minifyEnabled false
            shrinkResources false
            signingConfig signingConfigs.debug
        }
    }
